Specifically if you see it as a personal attack, consider looking up "signs of reference". It is a similar concept where you are delusional and believe that written signs are specifically designed and aimed at you.
This is probably good advice, though I am skeptical it would help. I think it would be helpful if you could tell me which elements that they may be able to help me with.
I would actually recommend taking your post as-is to a therapist as a starting session. (I wouldn't bother with the HN conversation itself.) It's a good starting point.
I'd say this... going to see a therapist once is not itself a commitment. If after the first time you don't feel like it's going to help, you will be free to stop. But I do believe there is some significant and true help that you can get from one... even if I am very reluctant to put into words the reasons why I believe that. I apologize for that, but I am trying my best to be helpful, and to not hurt you unnecessarily or out of unprofessional clumsiness.
On the self-help front, you may want to pursue mindfulness studies, with an eye towards the sort that helps you interrogate your own mind about why you feel the way you do. You may be surprised where that leads. Studying stoicism or other philosophies around acceptance may also help.
However, let me both open and close with the suggestion that professional help may be worthwhile. I do not mean that in a bad way, but a helpful way. I am all about self-help and independence and learning things and doing my own thing, but there's a limit to how far that can reach and sometimes you need direct external help.
